CVE-2020-15707 8 Canonical, Debian, Gnu and 5 more 15 Ubuntu Linux, Debian Linux, Grub2 and 12 more 2021-09-13 4.4 MEDIUM 6.4 MEDIUM
Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. These could be triggered by an extremely large number of arguments to the initrd command on 32-bit architectures, or a crafted filesystem with very large files on any architecture. An attacker could use this to execute arbitrary code and bypass UEFI Secure Boot restrictions. This issue affects GRUB2 version 2.04 and prior versions.
CVE-2019-7305 3 Canonical, Debian, Extplorer 3 Ubuntu Linux, Debian Linux, Extplorer 2021-09-13 7.5 HIGH 9.8 CRITICAL
Information Exposure vulnerability in eXtplorer makes the /usr/ and /etc/extplorer/ system directories world-accessible over HTTP. Introduced in the Makefile patch file debian/patches/debian-changes-2.1.0b6+dfsg-1 or debian/patches/adds-a-makefile.patch, this can lead to data leakage, information disclosure and potentially remote code execution on the web server. This issue affects all versions of eXtplorer in Ubuntu and Debian
CVE-2020-24512 3 Debian, Intel, Netapp 5 Debian Linux, Microcode, Fas\/aff Bios and 2 more 2021-09-09 2.1 LOW 3.3 LOW
Observable timing discrepancy in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
CVE-2020-24511 3 Debian, Intel, Netapp 5 Debian Linux, Microcode, Fas\/aff Bios and 2 more 2021-09-09 2.1 LOW 6.5 MEDIUM
Improper isolation of shared resources in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
CVE-2014-9751 6 Apple, Debian, Linux and 3 more 8 Macos, Debian Linux, Linux Kernel and 5 more 2021-09-08 6.8 MEDIUM N/A
The read_network_packet function in ntp_io.c in ntpd in NTP 4.x before 4.2.8p1 on Linux and OS X does not properly determine whether a source IP address is an IPv6 loopback address, which makes it easier for remote attackers to spoof restricted packets, and read or write to the runtime state, by leveraging the ability to reach the ntpd machine's network interface with a packet from the ::1 address.
CVE-2020-27830 2 Debian, Linux 2 Debian Linux, Linux Kernel 2021-09-07 2.1 LOW 5.5 MEDIUM
A vulnerability was found in Linux Kernel where in the spk_ttyio_receive_buf2() function, it would dereference spk_ttyio_synth without checking whether it is NULL or not, and may lead to a NULL-ptr deref crash.
CVE-2017-16872 2 Debian, Teluu 2 Debian Linux, Pjsip 2021-09-02 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Teluu pjproject (pjlib and pjlib-util) in PJSIP before 2.7.1. Parsing the numeric header fields in a SIP message (like cseq, ttl, port, etc.) all had the potential to overflow, either causing unintended values to be captured or, if the values were subsequently converted back to strings, a buffer overrun. This will lead to a potential exploit using carefully crafted invalid values.
CVE-2021-3731 2 Debian, Ledgersmb 2 Debian Linux, Ledgersmb 2021-08-27 4.3 MEDIUM 4.7 MEDIUM
LedgerSMB does not sufficiently guard against being wrapped by other sites, making it vulnerable to 'clickjacking'. This allows an attacker to trick a targetted user to execute unintended actions.
CVE-2021-3694 2 Debian, Ledgersmb 2 Debian Linux, Ledgersmb 2021-08-27 6.8 MEDIUM 9.6 CRITICAL
LedgerSMB does not sufficiently HTML-encode error messages sent to the browser. By sending a specially crafted URL to an authenticated user, this flaw can be abused for remote code execution and information disclosure.
CVE-2021-3693 2 Debian, Ledgersmb 2 Debian Linux, Ledgersmb 2021-08-27 6.8 MEDIUM 9.6 CRITICAL
LedgerSMB does not check the origin of HTML fragments merged into the browser's DOM. By sending a specially crafted URL to an authenticated user, this flaw can be abused for remote code execution and information disclosure.
CVE-2017-5715 7 Arm, Canonical, Debian and 4 more 221 Cortex-a, Ubuntu Linux, Debian Linux and 218 more 2021-08-16 1.9 LOW 5.6 MEDIUM
Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.
CVE-2018-3639 12 Arm, Canonical, Debian and 9 more 321 Cortex-a, Ubuntu Linux, Debian Linux and 318 more 2021-08-13 2.1 LOW 5.5 MEDIUM
Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4.
CVE-2021-35472 2 Debian, Lemonldap-ng 2 Debian Linux, Lemonldap\ 2021-08-11 6.0 MEDIUM 8.8 HIGH
An issue was discovered in LemonLDAP::NG before 2.0.12. Session cache corruption can lead to authorization bypass or spoofing. By running a loop that makes many authentication attempts, an attacker might alternately be authenticated as one of two different users.
CVE-2013-4852 5 Debian, Opensuse, Putty and 2 more 5 Debian Linux, Opensuse, Putty and 2 more 2021-08-06 6.8 MEDIUM N/A
Integer overflow in PuTTY 0.62 and earlier, WinSCP before 5.1.6, and other products that use PuTTY allows remote SSH servers to cause a denial of service (crash) and possibly execute arbitrary code in certain applications that use PuTTY via a negative size value in an RSA key signature during the SSH handshake, which triggers a heap-based buffer overflow.
CVE-2017-8379 3 Debian, Qemu, Redhat 3 Debian Linux, Qemu, Openstack 2021-08-04 4.9 MEDIUM 6.5 MEDIUM
Memory leak in the keyboard input event handlers support in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption) by rapidly generating large keyboard events.
CVE-2018-11806 4 Canonical, Debian, Qemu and 1 more 12 Ubuntu Linux, Debian Linux, Qemu and 9 more 2021-08-04 7.2 HIGH 8.2 HIGH
m_cat in slirp/mbuf.c in Qemu has a heap-based buffer overflow via incoming fragmented datagrams.
CVE-2017-7980 4 Canonical, Debian, Qemu and 1 more 12 Ubuntu Linux, Debian Linux, Qemu and 9 more 2021-08-04 4.6 MEDIUM 7.8 HIGH
Heap-based buffer overflow in Cirrus CLGD 54xx VGA Emulator in Quick Emulator (Qemu) 2.8 and earlier allows local guest OS users to execute arbitrary code or cause a denial of service (crash) via vectors related to a VNC client updating its display after a VGA operation.
CVE-2016-6662 5 Debian, Mariadb, Oracle and 2 more 12 Debian Linux, Mariadb, Mysql and 9 more 2021-08-04 10.0 HIGH 9.8 CRITICAL
Oracle MySQL through 5.5.52, 5.6.x through 5.6.33, and 5.7.x through 5.7.15; MariaDB before 5.5.51, 10.0.x before 10.0.27, and 10.1.x before 10.1.17; and Percona Server before 5.5.51-38.1, 5.6.x before 5.6.32-78.0, and 5.7.x before 5.7.14-7 allow local users to create arbitrary configurations and bypass certain protection mechanisms by setting general_log_file to a my.cnf configuration. NOTE: this can be leveraged to execute arbitrary code with root privileges by setting malloc_lib. NOTE: the affected MySQL version information is from Oracle's October 2016 CPU. Oracle has not commented on third-party claims that the issue was silently patched in MySQL 5.5.52, 5.6.33, and 5.7.15.
CVE-2018-1000115 4 Canonical, Debian, Memcached and 1 more 4 Ubuntu Linux, Debian Linux, Memcached and 1 more 2021-08-04 5.0 MEDIUM 7.5 HIGH
Memcached version 1.5.5 contains an Insufficient Control of Network Message Volume (Network Amplification, CWE-406) vulnerability in the UDP support of the memcached server that can result in denial of service via network flood (traffic amplification of 1:50,000 has been reported by reliable sources). This attack appear to be exploitable via network connectivity to port 11211 UDP. This vulnerability appears to have been fixed in 1.5.6 due to the disabling of the UDP protocol by default.
CVE-2017-10664 3 Debian, Qemu, Redhat 11 Debian Linux, Qemu, Enterprise Linux and 8 more 2021-08-04 5.0 MEDIUM 7.5 HIGH
qemu-nbd in QEMU (aka Quick Emulator) does not ignore SIGPIPE, which allows remote attackers to cause a denial of service (daemon crash) by disconnecting during a server-to-client reply attempt.
